Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for reusing textile dyeing and printing wastewater. Background Technology

[0002] Urban wastewater includes domestic sewage, industrial wastewater, and runoff, with industrial wastewater being the largest component, and dye wastewater being a significant source of industrial wastewater. The production of dyes consumes a large amount of water resources, and approximately 10%–20% of the dye is released into water bodies during production and use. Dye wastewater is characterized by large variations in water quality and quantity, high organic matter concentration, high color intensity, and strong alkalinity, making it challenging to treat. Therefore, research on dye wastewater treatment is of great significance.

[0003] Application number CN110627330A discloses a textile printing and dyeing wastewater treatment device for reclaimed water reuse, including an aerated biological tank. The upper part of the aerated biological tank is provided with a corresponding tank cover. The tank cover is connected to a water spraying mechanism near the aerated biological filter. Two X-shaped supports are provided opposite each other at the bottom of the tank cover. The two X-shaped supports are located on both sides of the aerated biological filter and are connected to a driving mechanism.

[0004] The above-mentioned solution uses a spray mechanism to pump water from the aerated biological tank to the top of the tank and spray it downwards, thus ensuring more thorough mixing of water and air. However, in practical applications, to simplify the treatment process and reduce operational costs, multiple steps such as aeration and flocculation are often required within a single tank. Different steps require different equipment, and existing treatment equipment cannot be interconnected, resulting in low equipment utilization and wasted resources. Summary of the Invention

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] In existing technologies, in order to simplify the processing flow and reduce operating costs, multiple steps such as aeration and flocculation are often required in a pool. Different steps require different equipment, and existing processing equipment cannot be interconnected, resulting in low utilization of the processing equipment and waste of resources.

[0051] Based on this, the present invention provides a device for reusing textile dyeing and printing wastewater, such as... Figure 1-5 As shown, it includes:

[0052] Feed tank 1, wastewater enters and collects in feed tank 1;

[0053] Treatment tank 2 is located below and connected to feed tank 1; in this embodiment, treatment tank 2 is located to the lower right of feed tank 1, and wastewater is collected in feed tank 1 and then enters treatment tank 2 for treatment.

[0054] The barrier net 3 is installed at one end of the feed tank 1 near the treatment tank 2. In this embodiment, the barrier net 3 is used to block solid impurities in the wastewater from passing through, so as to ensure the normal operation of subsequent wastewater treatment.

[0055] The drive assembly is used to clean the barrier net 3 and simultaneously stir and spray the wastewater in the treatment tank 2 to achieve flocculation, mixing, and aeration. The drive assembly includes a reciprocating section 41, a spraying section 42, a stirring section 43, and a drive motor 44.

[0056] The reciprocating section 41 is located on one side of the feed pool 1 and abuts against the barrier net 3; specifically, the reciprocating section 41 and the barrier net 3 are positioned opposite each other.

[0057] The spray section 42 is disposed above the treatment tank 2 and is connected to the reciprocating section 41 via a transmission mechanism.

[0058] The stirring part 43 is located below the spraying part 42 and extends into the treatment tank 2;

[0059] The drive motor 44 is connected to the reciprocating unit 41.

[0060] The specific working process of this embodiment is as follows:

[0061] Start the drive motor 44. The reciprocating part 41 is used to clean the barrier net 3 to prevent the barrier net 3 from clogging and preventing wastewater from entering the treatment tank 2. The reciprocating part 41 drives the spraying part 42 to rotate and achieve uniform spraying to achieve full aeration.

[0062] At the same time, the stirring section 43 and the spraying section 42 move synchronously to stir the wastewater in the treatment tank 2, accelerate the full mixing of flocculant and wastewater, and speed up the completion of flocculation.

[0063] To further ensure that wastewater flows stably towards the treatment tank 2 after entering the feed tank 1, the feed tank 1 is configured such that its bottom is inclined, with the lower end of the inclination close to the treatment tank 2. This configuration allows the wastewater to flow stably to the right, preventing it from accumulating in the feed tank 1.

[0064] To slow the rate at which wastewater enters treatment tank 2 and reduce pollution caused by splashing, the treatment tank 2 is configured such that the side closest to the feed tank 1 is concave and inclined to form a guide surface. Specifically, the guide surface is a smooth arc surface with a certain slope. After being filtered by the barrier net 3, the wastewater flows downward and slowly flows down the guide surface, avoiding splashing.

[0065] Furthermore, multiple staggered buffer ridges are provided on the guide surface to further reduce the water flow velocity, thereby preventing water from splashing too quickly.

[0066] Example 2

[0067] When wastewater enters the feed tank 1, it flows to the barrier net 3. Solid impurities in the wastewater (such as cotton fibers and textile scraps) are blocked and accumulate at the barrier net 3, causing blockage.

[0068] In view of the above problems, the present invention provides another embodiment, such as... Figure 1 and Figure 4 As shown, the reciprocating section 41 includes a rotating shaft 411, a drive rod 412, a moving block 413, and a scraper 414.

[0069] The rotating shaft 411 is connected to the output end of the drive motor 44; specifically, the drive motor 44 provides power for the rotation of the rotating shaft 411.

[0070] The drive rod 412 is mounted on the rotating shaft 411; thus, the drive rod 412 rotates under the drive of the rotating shaft 411 with the rotating shaft 411 as the center of rotation.

[0071] The movable block 413 is slidably connected to the top of the barrier net 3. The movable block 413 has a sliding hole for the drive rod 412 to slide. Specifically, the sliding connection between the movable block 413 and the barrier net 3 is as follows: a guide groove is provided at the top of the barrier net 3, and a guide block is provided at the bottom of the movable block 413, which is slidably connected to the guide groove, thereby limiting the sliding of the movable block 413. Furthermore, when the drive rod 412 rotates, it slides within the sliding hole to drive the movable block 413 to move back and forth.

[0072] The scraper 414 is connected to the bottom of the movable block 413 and abuts against the barrier net 3. Specifically, the reciprocating movement of the movable block 413 drives the scraper 414 to clean the barrier net 3 back and forth, preventing cotton fibers, textile scraps, etc., from clogging the barrier net 3 and affecting the passage of wastewater. In addition, multiple scrapers 414 can be provided to better and more comprehensively scrape solid impurities from the barrier net 3.

[0073] The working process of the reciprocating unit 41 in this embodiment is as follows:

[0074] When the drive motor 44 is started, the rotating shaft 411 begins to rotate, and then the drive rod 412 begins to rotate together with the rotating shaft 411. The drive rod 412 slides in the sliding hole, thereby driving the moving block 413 and the scraper 414 to make reciprocating motion.

[0075] Furthermore, when waste accumulates to a certain extent in the wastewater, the scraper 414, after scraping off the impurities from the barrier screen, will quickly cause blockage again under the impact of the wastewater. At this point, the treatment effect of the scraper 414 will deteriorate. Based on this, if... Figure 4 and Figure 5As shown, the moving block 413 is rotatably arranged with dispersing rods 9 located on both sides of the scraper 414. Specifically, the dispersing rod 9 includes a rotating rod and dispersing blades. When the rotating rod rotates, after being processed by the scraper 414, the dispersing blades can agitate and disperse impurities in the wastewater flowing to the front of the barrier net 3, allowing solid impurities to adhere more slowly to the barrier net 3. Thus, the combined effect of the scraper 414 and the dispersing rods 9 improves the treatment efficiency. The dispersing rods 9 can rotate in several ways: First, driven by a servo motor, with the servo motor connected to one of the dispersing rods 9, and the two dispersing rods 9 connected by a conveyor belt, ultimately rotating. Second, driven by the impact force of the wastewater, with driving blades at the bottom of both dispersing rods 9. When the wastewater impacts, the driving blades rotate, causing the rotating rod to rotate, ultimately achieving the dispersing effect. It is known that the two rotation methods can be used selectively. When the impact force of the wastewater is large, the second rotation method is used and can save resources. In other cases, such as when the impact force is small, the dispersion rod 9 can be rotated by a servo motor.

[0076] Example 3

[0077] To ensure sufficient and uniform aeration in treatment tank 2, in this embodiment, water in treatment tank 2 is pumped to the top of treatment tank 2 and sprayed, so that the water and air in treatment tank 2 are mixed more thoroughly and the aeration efficiency is improved.

[0078] Specifically, such as Figure 1 and Figure 2 As shown, the spray unit 42 includes a water tank 421, a liquid inlet cylinder 422, a liquid distribution pipe 423, and a vertical pipe 424.

[0079] The water tank 421 is fixedly supported above the treatment pool 2 by a fixing frame, which is set on one side of the treatment pool 2. Specifically, the treatment pool 2 is connected to a water pump (not shown in the figure), and a filter screen is set at the connection between the water pump and the treatment pool 2. Then the water pump is connected to the water tank 421, so that the water pump draws the wastewater filtered by the filter screen in the treatment pool 2 into the water tank 421.

[0080] The liquid inlet cylinder 422 is rotatably mounted at the bottom of the water tank 421 and communicates with the water tank 421. The liquid inlet cylinder 422 is connected to the rotating shaft 411 in a transmission manner.

[0081] There are multiple liquid distribution tubes 423, all of which are connected to the liquid inlet cylinder 422. Specifically, the liquid distribution tubes 423 are L-shaped and rotate with the liquid inlet cylinder 422. In this embodiment, there are three liquid distribution tubes 423. It can be understood that the number of liquid distribution tubes 423 is not limited and can also be two, four, or five, etc.

[0082] There are multiple vertical tubes 424, each of which is ball-connected and connected to a corresponding number of dispensing tubes 423. Specifically, the number of vertical tubes 424 corresponds to the number of dispensing tubes 423, and the number of vertical tubes 424 can rotate on the dispensing tubes 423.

[0083] In this embodiment, an aeration pipe is installed in the treatment tank 2, and air moves from the bottom of the tank to the surface of the tank; at the same time, water in the water tank 421 enters the liquid inlet cylinder 422, and the liquid inlet cylinder 422 is divided into three liquid distribution pipes 423. The wastewater in the three liquid distribution pipes 423 is transmitted to their respective vertical pipes 424 for spraying.

[0084] Further optimization involves circumferentially arranging multiple nozzles 425 on each of the vertical pipes 424 and the liquid inlet cylinder 422. The number of nozzles 425 can be 3-5, and each nozzle is connected to the corresponding vertical pipe 424 or liquid inlet cylinder 422. Specifically, all the nozzles 425 face the treatment tank 2.

[0085] Specifically, the working process of the spray unit 42 is as follows:

[0086] Water in water tank 421 enters inlet cylinder 422. Part of the water in inlet cylinder 422 is sprayed out through bottom nozzle 425, and the other part is diverted to three distribution pipes 423, then transmitted to their respective vertical pipes 424, and finally sprayed out from nozzles 425 on vertical pipes 424.

[0087] Example 4

[0088] In addition, when carrying out coagulation treatment, it is often necessary to add coagulant and set up a stirring unit 43 to fully mix wastewater and coagulant.

[0089] Based on embodiment 3, the present invention provides another embodiment, such as... Figure 1 and Figure 6 As shown, the stirring unit 43 includes a driving wheel 431, a driven wheel 432, a fixed ring 433, and a stirring rod 434.

[0090] The drive wheel 431 is sleeved on the liquid inlet cylinder 422;

[0091] There are multiple driven wheels 432, which are respectively sleeved on multiple vertical tubes 424 and all mesh with the driving wheel 431; specifically, the number of driven wheels 432 corresponds to the number of vertical tubes 424. In this embodiment, there are three driven wheels 432.

[0092] The fixing ring 433 is fixedly installed at the bottom of the water tank 421, and the inner ring side of the fixing ring 433 is provided with a rack that meshes with multiple driven wheels 432;

[0093] Multiple stirring rods 434 are provided, and the multiple stirring rods 434 are respectively connected to the bottom of multiple vertical pipes 424 and liquid inlet cylinder 422. Each stirring rod 434 has multiple stirring blades 435 arranged circumferentially.

[0094] Specifically, the specific working process of this embodiment is as follows:

[0095] In Example 3, the inlet cylinder 422 is connected to the drive shaft. Specifically, the transmission method can be belt drive or sprocket and chain drive, etc. Therefore, the inlet cylinder 422 starts to rotate, which in turn drives the drive wheel 431 to rotate, ultimately driving the three driven wheels 432 to rotate between the fixed ring 433 and the drive wheel 431. The driven wheels 432 then drive the vertical pipe 424 to rotate. The vertical pipe 424 rotates in a circular motion around the inlet cylinder 422 while rotating on its own axis. This rotation is similar to planetary gear rotation. Finally, the stirring rods 434, which are connected to the multiple vertical pipes 424 and the inlet cylinder 422 respectively, agitate within the treatment tank 2 to fully mix the coagulant and wastewater.

[0096] It is understood that while agitating, the air and wastewater are fully combined for aeration. In addition, the rotation of the liquid inlet cylinder 422 and the three vertical pipes 424 drives the corresponding connected nozzles 425 to rotate and move. Compared with the existing fixed spraying, this embodiment sprays while moving and rotating, which can further improve the aeration efficiency.

[0097] Example 5

[0098] When the barrier net 3 accumulates a certain amount of solid waste, it is necessary to clean up the waste to ensure the normal operation of subsequent wastewater treatment.

[0099] Based on this, the present invention provides another embodiment, such as... Figure 1 and Figure 3 As shown, a waste collection box 5 is provided at the bottom of the feeding pool 1, and a feed inlet 6 is provided at the top of the waste collection box 5. Specifically, after the feed inlet 6 is opened, solid impurities enter the waste collection box 5 for collection under the action of gravity.

[0100] Furthermore, the waste collection box 5 is rotatably equipped with a baffle 7 for opening or closing the feed inlet 6. Specifically, a hydraulic rod 8 is rotatably mounted on one side of the waste collection box 5, and the telescopic end of the hydraulic rod 8 is rotatably connected to the bottom of the baffle 7.

[0101] When closed, the hydraulic rod 8 extends, causing the baffle 7 to rotate clockwise until the baffle 7 reaches a horizontal position, thus completely blocking the feed inlet 6.

[0102] When opened, the hydraulic rod 8 retracts, causing the baffle 7 to rotate counterclockwise and finally open the feed inlet 6, allowing solid impurities to enter the waste collection box 5 stably.

[0103] The specific working process of this invention is as follows:

[0104] By setting a drive motor 44, the three processes of cleaning the filter screen, fully aerating the treatment tank 2, and stirring the treatment tank 2 are carried out in a coordinated manner.

[0105] Specifically, when the drive motor 44 is started, the rotating shaft 411 begins to rotate, and then the drive rod 412 begins to rotate together with the rotating shaft 411. The drive rod 412 slides in the sliding hole, thereby driving the moving block 413 and the scraper 414 to make reciprocating motion.

[0106] In addition, the inlet cylinder 422 is connected to the drive shaft, causing the inlet cylinder 422 to rotate. This rotation drives the drive wheel 431 to rotate, which in turn drives the three driven wheels 432 to rotate between the fixed ring 433 and the drive wheel 431. The driven wheels 432 then drive the vertical pipe 424 to rotate. Finally, the stirring rods 434, which are connected to the multiple vertical pipes 424 and the inlet cylinder 422, agitate the coagulant and wastewater in the treatment tank 2 to fully mix them.

[0107] Water in water tank 421 enters inlet cylinder 422. Part of the water in inlet cylinder 422 is sprayed out through bottom nozzle 425, and the other part is diverted to three distribution pipes 423, then transmitted to their respective vertical pipes 424, and finally sprayed out from nozzles 425 on vertical pipes 424.

[0108] Furthermore, the agitation also allows air and wastewater to fully combine for aeration. In addition, the rotation of the liquid inlet cylinder 422 and the three vertical pipes 424 drives the corresponding connected nozzles 425 to rotate and move.

[0109] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
